You need to get a sending unit for a gauge instead of the light. I would recommend the dealer. DO NOT INSTALL this without changing the oil pressure sending unit first, if you do it will fry the oil gauge. James
Just to be on the save side I probably wouldnt do the swap until I got the sending unit. While Im thinking about it, the last few days my speedo has been reading anywhere between 45-65 lately, just in town, how can I fix this little problem? It just jumps around and makes a little buzzing noise.
You probably have a bad speedo cable and speedo gear in the trans. If the cable binds up, sometimes it ruins the plastic gear in the trans. James
